Now, smaller entities do understand the need for encryption and that’s why Let’s Encrypt is such a good initiative.

Large entities that have traditionally used paid certificates have no reason to switch to Let’s Encrypt so the 2 markets barely overlap.

If they did, the traditional CAs would be much more aggressive against LetsEncrypt.

According to the EFF’s article here, Let’sEncrypt is only third in the sense that larger websites generate more traffic therefore, without having several big hitters under their certificates, they will always score lower.

On the other hand, if we’re just looking at the raw number of certificates, which in many cases may include duplicate or inactive certificates, Let’s Encrypt is in fact in the lead.
